"This connection has limited or no connectivity. "
Good morning,
Our client computers have the problem and they could not connect to our network or resources. They got this message ""This connection has limited or no connectivity."
We used the command ipconfig /release (renew). We also reboot the router at the remote site but it did not work.
could you please give me some hint?
Thank you

Can you run ipconfig /all and paste the output here? Usually this is the result of a faulty Gateway IP.

It should be DHCP issue because I did following steps already
1) Make sure I have good connection.
2) Check the hardware and settings.
3) Make sure the DHCP is working.
4) For the test, I can assign static ip. The static ip works, it is possible DHCP issue

DHCP client had worked before this issue. What logs do I check in Event Viewer?
Thank you

If all your client computers using DHCP are failing to get a valid ip address viewable via "ipconfig /all" (Should be something other than 169.254.x.x) and performing an ipconfig /renew /release does not provide an error like "Could not contact DHCP Server" than your DHCP server (probably your router) is not assigning addresses correctly or it is out of available addresses.

I run the ipconfig /all and get the ip other than 169.254.x.x and performed /renew /release and i got the the message "Could not contact DHCP server"
Looks like the DHCP server isn't responding to requests for addresses. Is your router acting as your DHCP server or do you have a seperate server in your environment?

Other computers in that site work. There are only computer got that message and could not get the connection. However, I assign the static Ip, it works
dongocdung may apologies your initial question indicated it was all computers at the site and not just one. Try reparing the IP Stack on that computer via
1. Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
2. In the command prompt window that opens, type type the following commands, each followed by the Enter key:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
3. Reboot the machine.

i have a question. We have two DHCP servers at HQ. They have the same IP range on DHCP servers. Does it cause that issue?
"i have a question. We have two DHCP servers at HQ. They have the same IP range on DHCP servers. Does it cause that issue?"
What do you mean? I need a better picture of your environment. Is the remote network on a different subnet? If so they wouldn't be able to talk to the DHCP servers at hq without a DHCP Relay agent or bootp router.
Is there a recent change with your DHCP configuration that has taken place before this problem started?
The DHCP Servers at HQ can have the same range but half of the addresses should be excluded. For example you set the scope on both Servers to 192.168.1.0/24 but then exclude say addresses 128-255 on one and on the other exclude addresses 0-127. That way they don't conflict.
However in your case the client in question can't contact any DHCP Server which again would be indicative if you don't have a DHCP server on that subnet and no relay agent.

The remote network is on the different subnet but they can talk to DHCP servers at HQ. there are only three computers at remote site have that issue. There is not recent change in DHCP configuration. In two DHCP servers, i saw they release the same IP adress range. That is why I think computers get the same IP. It causes the connection has limited or no connectivity.
thank you
thank you
Review your DHCP Configuration and Confirm the DHCP Relay agent is correctly forwarding queries.
Like I said if you have two DHCP servers then you can have the scope set the same just make sure one is excluding half of the addresses that the other one is excluding.

I just configure the split scope. I hope it works
